Answer:
A. 24%
Explanation:
The number of licensed drivers in four samples taken from a population of students are given by:
Sample Size Number of Licensed Drivers
25 7
50 8
75 18
100 25
The number who are licensed drivers is the ratio of the sum of the total licensed drivers of each sample divided by the total number of sample.
Assume Licensed Drivers is x
Hence, we get:
x = 7 + 8 + 18 +20 / 4
x = 53 / 4
x = 13.25
which is closest to 18
Hence, the answer is: 18 / 75 x 100 = 24%
